--------------------------------------
I've observed another occurrence of this test timing out, over on
https://builds.apache.org/job/HBase-PreCommit-GitHub-PR/job/PR-1786/3/
The failure message is cryptic, but I think i found the issue. There appears to
be a timeout set in some kind of secret manager, which is too aggressive for
this mini-cluster test. The last component of the mini-cluster, MapReduce, is
finally available at T+273501ms -- ~4.5 minutes after process launch. This is
out I interpret the log line
{noformat}
2020-06-02 03:20:49,252 INFO [Thread-223] server.Server(419): Started @273501ms
{noformat}
a scant 20ms later we get
{noformat}

These thread group names have no meaning to me.
